    Migrating application from Websphere to Jboss

    Saurav Sharma Newbie

      I am trying to port/migrate my WebShpere based application to JBOSS and followed thru Wiki examples - work with MQ.

      Application has 1 MDB let say childMDB which listen on Q_IN and parent of this MDB say parentMDB is an abstract class with one method to send message further.In ejb-jar.xml & jboss.xml - defined childMDB.

      Problem comes when I drop the message in queue the log reflects error with respect to Parent Class - NoClassDefFoundError-parentMDB.

      Just like wiki example(MDB) I bundle everything in jar file instead of .ear or .war file.

      Am I missing something in deployment descriptor or issue with class loader?

          It usually helps to post the full stack trace.

          And post the contents of you jar file. Use:

          jar -tf xxx.jar

          Also, state which version of JBossAS you are using.

            Here is the stack trace. I am using JBOSS-4.2.2 GA version.

              Peter Johnson Master

              It found the parent class just fine. Note the first line of the stack trace:

              at gov.uspto.ram.agency.mdb.AbstractEaiMDB.onMessage(AbstractEaiMDB.java:46)

              Could you post the code for the onMessage method and identify line 46?

              • 4. Re: Migrating application from Websphere to Jboss
                Saurav Sharma Newbie

                Thanks PeterJ, You were correct ,it's the problem with the class in onMessage method.Here is the code

                public void onMessage(javax.jms.Message mesg) {
                try {
                payGovJMSUtil = PayGovJMSUtil.getInstance();
                processMessage(mesg);
                } catch (Exception e) {
                e.printStackTrace();
                throw new EJBException(e.getMessage());
                }
                return;
                }


                But i copied the jar file in which this class(PayGovJMSUtil) exist in server deploy folder along with MDB jar. Looks like its not getting.Please tell me what is the class loader policy and sequence in JBOSS and which is the correct place to put helper jars.

                  I assume that PayGovJMSUtil is in some other jar file containing various business and utility classes that will also be required. If so, the best thing to do is create an ear archive containing both the utility jar file and the ejb jar file.
